Recent Experimental Results for the Dark-Matter Search at the Large Hadron Collider

Recent results from the dark-matter search at the Large Hadron Collider (LHC) are discussed in this review. Dark matter is one of the most veiled mysteries in current particle physics, and it cannot be explained using the Standard Model (SM). In attempts to discover dark matter, various theoretical and experimental approaches have been used and efforts have expended during the last several decades. Dark matter can be produced at the LHC, and the event signature from dark matter can be distinguished from the SM backgrounds. This paper presents recent results from the ATLAS (a toroidal LHC apparatus) and the CMS (compact muon solenoid) at the LHC on the mono-X search and the dark-photon search.
